When the mechanical outlet control device controls to turn on the first outlet passage, the sensor detects water flowing in the first outlet passage, whether the electromagnetic valve 32 opens or not, the central controller switches the electromagnetic valve 32 to normal close state immediately. So that the mechanical outlet is prior than the electronic outlet, two outlet modes are independent that they would not interfere to each other. And with the mechanical outlet, even if the electronic outlet fails, the kitchen tap can be still normally used.

In this embodiment, the electronic outlet control device 2 is provided with rationed outlet function, in detailed, it comprises an electronic outlet control switch 32, a volume option switch 22; the second outlet passage is further disposed with a volume meter 33, one end of the second outlet passage is cool water inlet, the other end is connected to the outlet of the kitchen tap;

The volume option switch 22 is linked to the encoder, the encoder is disposed with an unlimited outlet gear and a plurality of rationed outlet gears.

The electronic outlet control switch 21 and the volume option switch are independent, when the volume option switch 22 drives the encoder to a proper outlet gear, operating the electronic outlet control switch 21 can make the central controller turn on the electromagnetic valve 32, the volume meter 33 starts to count; when the volume meter 33 counts to the target volume set by the encoder, the central controller turns off the electromagnetic valve 32, thus achieving rationed outlet.

In this embodiment, the volume option switch is a rotating ring 22 disposed at one side of the outlet portion of the kitchen tap, the rotating ring 22 is disposed with a volume dividing ruler 221, the outlet portion of the kitchen tap is disposed with a marker 222. the volume dividing ruler 222 is disposed with a scale C corresponding to the unlimited outlet gear and scales 0.5 L, 1 L, 1.5 L, corresponding to the rationed outlet gears; when the rotating ring 22 rotates to make the scale of the volume dividing ruler align with the marker, it indicates the present outlet flow volume.

Furthermore, when the rotating ring 22 rotates to one side, the encoder rotates to the unlimited outlet gear; when the rotating ring 22 rotates to the other side, the encoder rotates to one of the rationed outlet gears. By different rotating directions, the user can choose the unlimited outlet gear or the rationed outlet gear easily, the user experience is better.

If the mechanical outlet control device 1 is closed and the user turns on the outlet control switch 21 by accident, water will flows out of the kitchen tap, that is to say, when the mechanical outlet control device 1 is closed, the electronic outlet control device 2 is always available, this situation isn't suitable, misoperation easily happens when the user is washing the kitchen tap. To solve the problem, this embodiment is further provided that: when the encoder is rotates to the unlimited outlet gear, the central controller switches the electromagnetic valve 32 to normal close state. Therefore, the user just needs to rotate the rotating ring 22 to the unlimited outlet gear to turn off the electronic outlet mode, so that the kitchen tap will turn to a mechanical traditional tap, the tap would not turned on when washing the tap or the washbasin.

In this embodiment, the electronic outlet control switch 21 is a touch switch, press switch or infrared switch are available, they are simple substitutions of this embodiment that it would not be further described.

As a traditional kitchen tap has cool water outlet and hot water outlet two modes, for that in this embodiment, the first outlet passage comprises a cool water inlet, a hot water inlet and a mixing water outlet; the mixing water outlet is connected to the second outlet passage, the sensor 31 is disposed at the end of the mixing water outlet of the first outlet passage.

Correspondingly, the mechanical outlet control device 1 comprises a handle, when rotating the handle, the first outlet passage is open, when continuously rotating the handle, the proportion of cool water of the first outlet passage decreases and the proportion of hot water increases to make the outlet temperature of the outlet device rise.

The working process of the kitchen tap is as follows:

1. The mechanical outlet control mode: when rotating the handle, the first outlet passage is open, water inside is cool water; when continuously rotating the handle, the flowing area of the cool water inlet is decreased, the flowing area of the hot water inlet is increased, form the mixing water in the first outlet passage. The outlet temperature of the kitchen tap rises with the rotating of the handle. When the sensor 31 detects water flowing in the first outlet passage, the electromagnetic valve 32 is always turned off, however the user adjusts the rotating ring 22 or touches the touch switch, the electronic outlet mode would not be triggered. It guarantees the highest priority of the mechanical outlet mode, the outlet mode is single and stable.

2. The electronic outlet control mode: be sure that the handle is in close state, the sensor 31 detects no water flowing in the first outlet passage. when the user rotating the rotating ring 22, it drives the encoder to the proper outlet gear, touching the touch switch can make the central controller turn on the electromagnetic valve, the volume meter 33 starts to count; when the volume meter 33 counts to the target volume set by the encoder, the central controller turns off the electromagnetic valve 32 to achieve rationed outlet.

3. Close mode: when the user rotates the rotating ring 22 to unlimited outlet mode, the electronic outlet control mode is turned off, if the mechanical outlet control device is turned off, no water flows out of the kitchen tap.

It should be noted that, this embodiment takes rationed tap for example, other electronic-mechanical double-switch taps are available to apply with above control idea, they are within the scope of the present invention.
